<u>The Virus:</u>
A virus can be defined as a malicious program, that breaks into the computer without the consent of the user and sometimes even without the knowledge of the user. Viruses are also of different types and categories.
There are certain kinds of malware and spyware that enter a computer and start encrypting the user's data. Generally, a user gets to know about the existence of a virus when the computer programs begin to misbehave. Some files get corrupted and the user can't access them anymore.
Some files and programs may also get deleted as if they weren't even present on the system. But in case someone has installed good anti-virus software, they will get a notification as soon as some file containing some kind of virus enters the computer.
<em>Network change in larger organization follows hierarchy of approval.
</em>
<em>Hierarchy of approval will start from the lowest department. The lowest department must prepare a written proposal, stating that there is a need for the network upgrade. Attachments such as proposed price list for the new equipments to buy also comes up with the proposal. Once that all documents are prepared, signatures from approval departments must be gathered. Each signature should be present and complete.

Answer:
Following are the program in the Python Programming Language:
def check(num): #define function
if(num.isdigit()): #set if statement
return "yes"; #return yes if condition is true
else:
return "no";# return no if condition is false
string=input("Enter the numbers 0-9: ") #get input from the user
print(check(string)) #print and call the function
Output:
Enter the numbers 0-9: 1995
yes
Enter the numbers 0-9: 42,000
no
Explanation:
Here, we define a function "check()" and pass an argument in its parameter "num" inside the function.
- we set if-else conditional statement and check the value stored in the variable "num" is the digit by using built in function "isdigit()" then return "yes".
- Then, otherwise it return "no".
Finally, we get the input from the user in the variable "string" then, we call the function through "print()" function.
Answer:
void showSquare(int param){
}
Explanation:
In C++ programing language, this is how a function prototype is defined.
The function's return type (In this case Void)
The function's name (showSquare in this case)
The function's argument list (A single integer parameter in this case)
In the open and closing braces following we can define the function's before for example we may want the function to display the square of the integer parameter; then a complete program to accomplish this in C++ will go like this:
<em>#include <iostream></em>
<em>using namespace std;</em>
<em>void showSquare(int param);</em>
<em>int main()</em>
<em>{</em>
<em> showSquare(5);</em>
<em> return 0;</em>
<em>}</em>
<em>void showSquare(int param){</em>
<em>int square = param*param;</em>
<em>cout<<"The Square of the number is:"<<endl;</em>
<em>cout<<square;</em>
<em>}</em>
